摘要： A method for relaying data packets to a subscriber station (SS) by taking a relay station (RS) into consideration when a base station (BS) establishes a data packet scheduling is disclosed. According to the method, a data packet is relayed by RSs, which have a signal intensity greater than a threshold value for all RSs appointed by the BS. Each SS determines whether the SS receives the data packet directly from the BS or via an RS, based on signal intensities between the SS and the BS and between the SS and RSs, and feeds channel information corresponding to the determination back to the BS, thereby allowing the data packet to be transmitted.

摘要： A scheduling method and system is disclosed that divides scheduling between a base station and a mobile station into scheduling between the base station and a relay station and scheduling between the relay station and the mobile station, and performs the divided schedulings. In a radio communication system that transmits a signal of a base station to mobile stations located on a border of a cell by using a relay station, the base station having multiple antennas receives phase information of the respective antennas from the relay station having multiple antennas, compensates for phases of the respective antennas, and transmits data through the phase-compensated antennas. The relay station transmits only channel quality information of the mobile station, which has a high possibility of being selected by the base station among channel quality information of the mobile stations that belong to the relay station, to the base station.
